I fixed Cpu mode

[KintCark]

Hey when u enable Cpu Mode it still fails at cuda check at sertant parts I fixed it with 2 files one is src/animatediff/generate.py and the other is src/animatediff/pipeline/animation.py all u gotta do is change the (cuda) in brackets to Cpu in both those files u don't need to mess with the one by igpu and the torch.cuda.empty lines just the ones in brackets
